Ajax Hubs: choosing the right Hub

The central unit is the brain of the system. It receives signals from all devices, decides whether to trigger the alarm, and transmits information to your smartphone and to a monitoring center. Everything else about the installation depends on this choice: it's the first decision to make, and the hardest to go back on.

Comparison of Ajax Hubs

Hub 2 or Hub 2 Plus?

This is the most frequently asked question. The Hub 2 easily covers a house or apartment: 100 devices is already well beyond what a home actually uses.

The Hub 2 Plus is justified by three criteria. First, capacity: 200 devices, 200 users, and 25 security groups, which allows for independent arming of a storage area, a floor, or an annex building. Second, communication redundancy: four channels instead of two, with Wi-Fi adding to Ethernet and the two 4G SIMs. Finally, resilience: its 3.7 V / 3 Ah Li-ion battery provides about 15 hours of autonomy in the event of a power outage.

In practice: for a house or apartment, a Hub 2 is sufficient. For a business, office, warehouse, or connection to a monitoring center, choose a Hub 2 Plus.

Keypads, remote controls, and modules

This collection also includes system expansion modules: the MultiTransmitter, which integrates third-party wired detectors into an Ajax system, and transmitters that link to monitoring centers. Arming keypads have their own collection.

Jeweller radio range

The Jeweller protocol boasts up to 2,000 meters in open field between a device and the Hub. In a building, load-bearing walls, concrete slabs, and elevator shafts significantly reduce this value. The rule of thumb: always test the signal quality from the app, at the exact planned location, before fixing anything. If the signal is weak, a ReX repeater resolves the situation in almost all cases.

Frequently Asked Questions

Can I change Hubs later without buying new detectors?
Yes, all Jeweller devices can be re-paired with a new Hub. You only lose the reconfiguration time.

Is a SIM card required?
It's not mandatory if the Hub is connected via Ethernet, but it's highly recommended: the SIM takes over if the internet connection drops, which is precisely when a burglar acts.

Does the Hub work without a subscription?
Yes. Only connection to a monitoring center requires a contract.
